Hello aspirant,

You cannot become Surgeon after completion of B.Sc or M.Sc in Cardiology. To become a Surgeon you need first complete your MBBS course and then MD/ MS in specialization you are interested in and they if you are interested then can go for DM in super speciality specialization of your choice.

Minimum qualification required for MD/ MS is, candidates must appeared in entrance exam like NEET UG and secured MBBS seat and completed it from a recognised College or University are only eligible to appear for NEET PG and then to get MD seat. Then through NEET SS you can join DM in super speciality specialization.

So with just B.Sc or M.Sc in Cardiology you are not eligible to become Surgeon.
